Why I Duo Queue or Dynamic Queue in Ranked

From a perspective of a ranked duoer/dynamic queuer(Sorry I'm so bad at english ;-;) the reason why I dynamic/duo queue is because whenever I solo queue, or queue solo it takes a really long time to find a match! Unless I am support, but I dont really feel comfortable to take support in ranked just yet! So I usually queue with friends so the wait time is just a bit faster!
